NXT Performance

Had James round to remap our VW sharan.Great guy and very knowledgeable.Big difference in the car with much more power and torque.Would definitely use again if the need arises.

Had a my car remapped before, but main dealer wiped the map. Decided to have it done again as the fuel consumption had gone up on standard car.I shopped around and found JS who quoted a very competitive price, the saving compared to other mappers made me decide to have the gearbox mapped as well.The car is decidedly quicker with a super smooth gear change, fuel consumption has improved by a least 10%, but I reckon there’s more room for improvement once I decide to stop enjoying the added power. Also JS bench map the ECU, this a safer method than using the OBD port, a lot of other mappers charge extra for this. Excellent service, by a guy who cares about his work.

James came out to remap my Renault Master van in the same week as our discussion about it. He shared so much information with me and answered every question I had and more. I had a stage 1 remap and I couldn't be more happy with the results. It's honestly like driving a new van. Highly recommend getting in touch with James. Extremely professional service and a genuinely great guy who you can tell has a passion for his work which is a rare thing to come by these days. 5 stars from me.

Have taken a couple of cars to these guys now for remapping and hardware modifications, James is always quick to respond to any questions and has been great all throughout the process, even after the work has been completed. Top service from top guys.

I had NXT Performance come to do a stage 1 remap my Ford focus ST3 mk2James was so good with all the questions I need to know about the process .I had an absolute amazing service and very professional .The price was very competitive and unique to my car . ( Which that do for all cars )It was very clear and simple process with James talking to me throughout the process .He even done it in the rain and made sure I was happy.I can highly recommend you use NXT Performance .My car is totally different and very responsive after the remap was completed .Money well spent in my eyes

I found NXT performance on google, I enquired about some DPF/CAT work and some ECU changes + remap on my Golf GTD.James came back to me promptly with a very competitive quote, I went ahead with the work and Lee and James were great from start to finish.After the work was completed I asked James for some after sales support and he came out to me as he had another job not too far from where I live to make some tweaks to my map which was at no extra cost.Very informative, Great Communication, and went above and beyond my expectations.Thank you very much James & Lee!J.

Had some work done on my Vauxhall Astra which has made a huge difference and am very happy with the service received. James was very thorough with telling me the process and also kept me well updated throughout which made the whole service even better.Cheers for all your help!Will be sure to be in contact for any further work!

Had my 2006 passat tdi 140bhp for 12 odd years now and fancied a bit more power and better mpg when sensible. Phoned JS Remapping he was very professional and talked me through the whole process.Jaime came over one evening and transformed my car giving me approximately 40bhp increase which has made it even more of a joy to drive, I now have more torque for over taking grunt and better mpg on the motorway (when sensible).This is a couple of months on as i wanted to give an honest review.Thanks again to the JS Remapping for the great product and service I won't hesitate to use them again when I need to.

Had a DPF removal and remap with these guys fantastic bloke James worked with me and my ever changing mind was very professional got the job done in a day and must say a lovely car to be in now with no issues over 2 weeks later
